Abstract: The present invention provides an improved multimedia communication device within cloud computing techniques including a display mechanism for multimedia playing; an operation mechanism linking with the display mechanism for interpretation and implementation of the display mechanism; and a servo mechanism linking with the display mechanism for certification program of the operation mechanism and transmission of the list of multimedia service to the display mechanism; thus, the multimedia playing frequency channel located in our server cloud computing is detected at any time and the contents of the frequency channel are updated immediately; not only the needed frequency channel is quick found by an user, but also it ensures that all frequency channels located in our server cloud computing are normally linked by the user.

Abstract: The present invention relates to a video codec method with high performance comprising the following steps: 1. predicting the motion vectors in the blocks to be predicted through Median Prediction and Up-layer Prediction, 2. terminate the motion prediction in the blocks predicted once the predicted motion vectors are below a threshold value. Otherwise, 3. Sample data in the block to be predicted and then, based on the data sampled, determine a block best resembling the above block from which samples are sampled for a further OTA search to finish a block motion prediction. By such steps, the overall amount of video encoding processing is dramatically reduced and performance is improved without sacrificing video quality. In addition, we may make a more accurate motion prediction of the block to be predicted to avoid the wrong prediction that an OTA algorithm might result in when the motion vector is exceedingly large.
